3 5. Assessment of the current status of the biodiversity objects3

4 Learning objectives Participants have a clear understanding of the terms “key ecological attribute” and “stress”. They recognize and are able to explain the use of defining and assessing key ecological attributes and stresses in order to assess the actual status of the biodiversity conservation object`s functionality. Furthermore, participants have the skills to facilitate the process of identifying relevant key ecological attributes, identifying good indicators to measure their actual status and determining their desired future status. Participants have the knowledge and skills to identify relevant stresses to conservation objects with a team as well as to explain the role of key ecological attributes and stresses in assessing the vulnerability of the conservation objects. 5. Assessment of the current status of the biodiversity objects4

5 ? Outline What is the assessment of the current status of biodiversity objects? Why do we assess the current status of the biodiversity objects? How do we assess the current status of the biodiversity objects? Part a) Determination of key ecological attributes and functionality of the target systems Part b) Identification of current stresses that reduce the viability and integrity of the biodiversity targets Practical Tips 5. Assessment of the current status of the biodiversity objects5

6 ? What is the assessment of the current status of biodiversity objects? First part of the Systemic vulnerability and risk analysis Identification of more concrete elements that ensure the efficient and resilient functionality of ecosystems – Key ecological attributes relate to respective biodiversity objects – Stresses are the experienceable degradation of key ecological attributes 5. Assessment of the current status of the biodiversity objects6

7 ? Functionality of an Ecosystem … is a certain state of a system that is characterised by biological and ecological interactions of components that contribute to the system‘s efficiency and resilience No stress = high functionality = resilient Low functionality of a system = system prone to shift and change High functionality of a system = „healthy“ system Conservation goal To be mentioned: In reality, a certain level of disturbance and corresponding stress is always driving the evolution and adaption of biological and ecological systems (and is even needed so they can develop their adaptive capacity). 5. Assessment of the current status of the biodiversity objects7

8 ? Key Ecological Attributes Basic elements and properties of ecological systems They maintain function and provide necessary adaptation and resilience to cope with perturbations They relate to: Master factors → energy input, moisture, temperature, nutrients Biomass Networks Information 5. Assessment of the current status of the biodiversity objects8

10 ? Stresses Caused by threats Visible symptoms & mani- festations of degradation of key ecological attributes Loss of minimum levels of biomass, information and network due to insufficient availability or quality of master factors 5. Assessment of the current status of the biodiversity objects10 Result: Negative impact on resilience and adaptive capacity of biodiversity elements If stress is sustained → shifts or changes in system

11 ? Stresses Metaphor of a medical doctor and his examination of the patient It is the wound/ injury/ change of the body that is visible 5. Assessment of the current status of the biodiversity objects11

13 ? Why do we assess the current status of the biodiversity objects? Assessment as basis for strategies to improve or at least maintain the functionality of the ecosystem Create a comprehensive bridge between the ecosystem/ its elements and the stresses they are facing → build understanding for the necessity of conservation 5. Assessment of the current status of the biodiversity objects13 © Christina Lehmann 2014

14 ? How do we assess the current status of the biodiversity objects? Part a) Determination of key ecological attributes and functionality of the target systems Assessment follows 3 basic guiding principles 1.„Nature knows best“ Do not assume that there are better/more efficient ways of driving function and dynamics in natural ecosystems 2.Identify and correct negative anthropogenic influence that cause unnatural loss and change 3.Build natural but compromising strategies → natural character of original parent ecosystem + communities‘ needs and dependencies 5. Assessment of the current status of the biodiversity objects14

15 ? 1.Identification of key ecological attributes for all biodiversity objects List them on white cards For each biodiversity object in individual working groups or in plenary discussion possible Categorisation of KEA according to main categories (master factors, biomass, information, network) with scientifically experienced groups possible 5.

17 ? Guiding questions for identification of key ecological attributes  Which key characteristics are required for the functionality of the biodiversity object?  Which key characteristics would lead to the loss or total degradation of a biodiversity object when altered or missing?  Which key characteristics are required to ensure resilience of a biodiversity object and for it to have a certain adaptive and buffering capacity against disturbance and environmental change? 5. Assessment of the current status of the biodiversity objects17 How do we assess the current status of the biodiversity objects?

18 ? 2.Define indicators to measure the status of the key ecological attributes At least 1 indicator per attribute Measurability of generated indicators necessary Limit number of indicators to most significant and cost- effective ones In case of time and resource constraints → attention to representation of bigger systems within project area 5. Assessment of the current status of the biodiversity objects18 How do we assess the current status of the biodiversity objects?

19 ? S-U-M criteria for good indicators Sensitive: The change in indicator values must consistently correlate with changes in the condition to be managed, without showing any changes over time. Unambiguous: It is clear from the evidence and understanding that the indicator relates directly to the condition to be managed. Measurable: Possibility to take reliable measurements with reasonably simple and costefficient equipment or methods necessary. 5. Assessment of the current status of the biodiversity objects19 How do we assess the current status of the biodiversity objects?

20 ? 3.Establish an accaptable range of variation and a rating scale for indicators Natural variation as part of oscillation and dynamics of an ecosystem 5. Assessment of the current status of the biodiversity objects20 Check out: Holling Holling How do we assess the current status of the biodiversity objects? © Holling 2001

21 ? Consider ranging of indicators to categorise them → establish rating scale Rating scale created through initial distinction of 2 states (eg. Very good/good and fair/poor) and further splitting afterwards (e.g. very good = 4; good = 3; fair = 2; poor = 1) Natural variation is acceptable when very good or good Alert when indicators are below good 5. Assessment of the current status of the biodiversity objects21 How do we assess the current status of the biodiversity objects? © CEEM 2014

22 ? Guiding questions for the identification of range of variation  How much alteration in an indicator is acceptable/too much for a biodiversity object?  How much restoration is enough? 5. Assessment of the current status of the biodiversity objects22 How do we assess the current status of the biodiversity objects? Tipping point reached?

23 ? To be mentioned: Do not flounder at this stage of categorisation – as the emphasis of MARISCO lies on adaptive-management planning and knowledge mapping even in mediocre circumstances, alterations at a later point are possible. 5. Assessment of the current status of the biodiversity objects23 ? How do we assess the current status of the biodiversity objects?

24 ? 4.Determine the current and desired future status Provide indication of the current status (proxy data of indicators objectively collected or subjectively estimated) Project visionary future status of key ecological attributes → what status should the attribute be in after management strategies have been applied? 5.

25 ? Part b) Identification of current stresses that reduce the viability and integrity of the biodiversity targets Rationale: Understanding of how target systems are affected by threats Analysis and assessment of stresses of biodiversity objects according to considered key ecological attributes = Reflection on health of biodiversity objects Clustering of stresses and construction cause- effect-chains within „stress-network“ to identify most critical stresses 5.

27 ? Use: purple rectangular „MARISCO stress cards“ 5. Assessment of the current status of the biodiversity objects27 How do we assess the current status of the biodiversity objects? © CEEM 2014

28 ? Guiding questions to identify stresses  What kind of negative changes can be observed happening in the biodiverstiy object?  What are the signs of „disorder“ and „illness“?  Are there any critical changes to the status of environmental master factors, such as climate, soils or water?  Is there a loss of biomass, information or network within the system?  Is there a loss of network/ connectedness with other systems? 5. Assessment of the current status of the biodiversity objects28 How do we assess the current status of the biodiversity objects?

29 ? Practical Tips Try to define indicators as clearly as possible to avoid confusions while rating them It is crucial to focus concretely on the elements that are central and the function they carry in the conceptual model and system → try to avoid overlappings with neighbouring categories like „biodiversity objects“ or „threats“ because they confuse the model and make working with it more difficult → You might want to explain the following steps a bit already as this will increase the understanding why certain negative influences on the ecosystem are NOT stresses but threats that cause stresses 5.
